OMEGA’s PX26 Series pressure sensors feature state-of-the-art silicon technology which permits both sides of the diaphragm to handle liquids. A unique conductive seal between the silicon diaphragm and the plastic housing allows for wet/wet applications and lower production costs than typical gold wire silicon sensors. This new construction has a larger diaphragm than traditional silicon sensors, resulting in increased long-term stability.

Rated 3 out of 5 by from Sometimes OK but sometime not We bought this a month ago for our water pressure loop test, initally it was good and be sensitive to pressure drop changes and read correctly. However, after switching and squeeze air out of in and outlet lines, found the connection was easy to break and get wet so readings were really out of range.

Rated 5 out of 5 by from Pressure measurements inside small ID thin tubing We use these pressure gauges in combination with the PLATINUM™ Series Digital Panel Meters (DP8PT-006) to determine the pressure inside thin flexible tubing as water is flowing inside. WE use three of these pressure gauges along the tubing and can determine the pressure changes with the experimental conditions. They work well and are responsive.

1. Can a PX26-001GV to be used to measure -1 to 1 psi? (negative pressures) 2. The NI asks for bridge configuration and nominal resistance. Is it full bridge type? Is the Nominal resistance the input or output resistance?

Asked by: blackpotato
You can measure vacuum with these sensors. The output signal will have negative polarity. Your NI is assuming the input will be from a foil strain gage bridge with a nominal balanced bridge resistance of 120 or 350 ohms (both the input and output the same resistance value) The PX26 is not a foil strain gage bridge. Input resistance 7.5Kohms. Output resistance 2.5Kohms.

We are using the +- 1 psi differential pressure sensor. When we connect the pressure sensors as shown in the data sheet (with 10V input), we are measuring the ouput voltage to 2.6V. Do you know why, is it an off-set voltage?

Asked by: EngineerLasse
Are you wiring the sensor differentially (power connections separate from signal connections). If the negative signal connection and the negative excitation are connected to a common point you will get a high voltage signal output. If the connects are not commoned together you most likely have damaged sensor sensor

Can you recommend a voltage regulator which would be a good fit for this transducer? I looked up the specs but cannot find one which provides output as low as 0.1 V with an input of 10V

Asked by: Shishir
Nominal excitation for the PX26 Series sensor is a regulated 10VDC. With 10VDC applied the output signal from the PX26 would be 0 to 16.7 mVDC for the 1 psi unit, 0 to 50 mVDC for the 5 psi unit and 0 to 100 mVDC for the 15, 30, 100, and 250 psi units. Current draw from the power supply would be 2 mA per unit. We offer a regulated power supply part# FAR-1 that would supply regulated 10VDC.
